lf-iMoLutted'inppn the carriage befr ffl-are -a series. of engagers 12. The bar 2 has drilled therein a series of? holes 1 3 .whichmre three -lettezmsteps of; Athe typewriter apart and each engager 12 is furnished With-three holes-1l. therein Each. engager is fastened to..tl1e frmneworkbyi menne of a stud l5 which passes through one,of the bar holes v1 3 and enters into the engager holes-1a.. It is evidentithatby. means of this arrangement the engagers may be gir-en :my desired arbustmentf-upon thercarriugebar.- I l mEach :engager is composed ofanangle plate l'on which is mounted e screw 17 and upony whiel'iorotates the engager plate 1S.

This normal position is determined by the Contact of an edge of the that it cannot yield under the impactof the engagers, so it is thelengagerls that'yeild They therefore swing about the screws 17 thus drawing their front noses 42- backward. Upon the retraction of the carriage and the carriage bar 2 to the right, it is the engagers that cannot yield and the disconnector that can. Therefore during the retraction of the carriage bar the disconnector turns about its pivot and the engagers pass over it.v Upon a close examination of Fig. 2, it will be seen that the front noses 42 of the three engagers at the left are shorter than the front nose 43 of the engagers at the right. Moreover, an examination of the same figure will show that the left wall 50 of the totalizer 9 is not as long as the left wall 51 of totalizer 10. The right walls of the totalizers are' cut away in order not to interfere with the noses of the engagers.

In operation, the mechanism functions as follows: Assume the carria e bar to be at its extreme right position with its left-most engager to the right of the totalizer 10. Upon the operating of the keys, the carriage bar will advance during the letter space advance of the typewriter. After some time the nose 42 of the left-most engager will come opposite the left Wall 51 of the totalizcr l0, but as both engager and wall are short, they will pass each other Without contact and therefore without any action. The `further operating of the typewriter brings the engager opposite the left wall 50 of tolalizer 9. Here the engager is short, but the left wall 50 is long enough to make up for it, and therefore contact will be made by the engager and the left wall 50, and the further letter space advance of the bar will cause a corresponding movement in the totalizer 9. An examination of Fig. 1 will shor that in the normal position the wheels G0 of the totalizers do not engage the master wheels, but that a small motion to the left will bring these wheels 60 into engagement with the master Wheels. This small motion is now imparted to the totalizer 9 by the further motion of the carriage bar. The wheels of the totalizer therefore en gage the master wheel. The further continued 42 ,nose 42 and wall 50 is therefore broken. The y totalizer 9 under the influence of its spring the bringing of the back edge 40 of the engager against th'e top 41 of the disconnector and theconsequent drawing-in of the nose as above explained. The contact between 11 is immediately retracted to the right. Furthermovemen't of the carriage bar results in again picking up and pushing forward totalizer 9 by the second engager, etc. There is therefore computed in totalizer 9 the sum of the numbers thus inserted on the calculator keys. During all this time, 'the grand totalizer 10 has been stationary. However, ,whenthe parts reach the position shown in Fig.'2, thatis, when the short nose 42 engages the long wall 50, and similarly the long nose 43 engages the short wall 51, then both totalzers will contact simultaneously with the engagers, and any further movement of the carriage bar to the left carries both totalizers over their master wheels to be operated by them.

Assume that the handle 5, up to this time. has been in position one (l), (that is, wheel 4 rotates 'in the adding direction) and that thehandle be now shifted to position three (3) (so that the wheel 4 now rotates in a subtracting direction and the wheel 3 in an adding direction). Then the operating of the keys would now result in subtracting the total out of totalizer 9, and the simultaneous inserting thereof into totalizer l0. This would complete the operation for one line. During the writing` of the next line, there would again be calculated upon the totalizer 9 the sum of the numbers written horizontally. which new total would again he transferred to the totalizer 10. 'lotalizer l() would therefore show the sum of the two totals, each of which was previously derived by the totalizer 9. lt is thus evident that after any number of lines being Written and computed, totalizer l0 will always show the grand total of all the totals previously and `individually computed by totalizer 9.

During the printing of the grand total th(` handle may be shifted to position two (2) and the reversing shaft be set to subtract. Master wheel 3 will therefore operate to subtract the grand total out of the grand totalizer while master wheel 4 will remain stationary and therefore will not affect the subtotalizer.

As stated above, similar results, namely the computation of totals and grand totals. have been accomplished by other mecha nisms, for instance, by the mechanism shown in the above cited Patent, No. 893,717. But the mechanism .shown here is quite different from the above in some of its principles. and its parts are more strongly built. For instance, the totalizers are mounted upon i place ot' calculation.

short bars instead of long trucks, and can easily be made rigid and thus coperatc with the mating gears much more accurately.

It may be noticed by a comparison of the mechanism shown in this application with the mechanism described in my previously issued Patent No. 893,717, that the reciprocation of the totalizers is accomplished in a dilferent manner. In said patent, thereciprocatory totalizer has a pawl mechanism mount-ed thereon, which mechanism is oontacted by members fastened to the printing carriage. The totalizer is a comparatively complicated piece of mechanism, and in practice it has been found advisable to keep it as simple as possible. I have therefore so constructed the parts that the paWl mechanism is mounted not upon the totalizer but upon the printing carriage and this is one of the objectsof my invention.

There has been described above a calculator containing two totalizers, one reciproeating for the total of numbers printed in a horizontal line, and the other traveling for.

the grand total of the various line totals. It is evident that it need not be the totalizers that travel. The mechanism could be modi fied without departing from the spirit of my invention. For instance, it might be the master wheels that move and the totalizeis that remain stationary. Thus moditied there would be a reciprocatory master Vwheel for the line totals, and a traveling master wheel for the grand totals, and the cngageis mounted upon the carriage bar would then be made operative not upon the totalizcrs, but upon the master wheels.

But even this does not exhaust the possibilities oi easy modification, for it is evident that neither totalizers nor master wheels need more. They may be replaced h); mechanism in which there is a traveling connector which determines the decimal Such mechanism has heen shown in several patents, as for instance. Patent No. 946,366, issued January l1. 1010. In all of these cases, however. there must always be some member which moves to determine the decimal place of calculalion, and this` member is called the decimal carriage, whether that decimal carriage he a llraveling totalizer, a traveling master wheel, or a traveling connector.

As far as I am aware, I am the first one To have constructed a mechanism including therein a decimal carriage reciprocating for tho calculation ot' the totals ot numbers printed iu a horizontal liuc. and another decimal carriage which remains .stationariv duringr the calculation oi' the liuc totals, but moves during the calculation oi the rand totals. Viewed from another standpoint, it might be said that this application is the first to Ishow a mechanism including a sub- ,"and horizontal total decimal carriage and a grandtotal decimal carriage; the sub-total reciproca+- ing during the accumulation oi' the numbers whose sum composes the` sub-totals, the grand-total decimal carriage remaining stationary, meanwhile, and both decimal carriages traveling during the accumulation ot the grand totals.

While this application has so far described engagers whoseengager plates are all in the same plane, and which therefore travel through the same path, it 'is evident that this need not be so, but that some of the engagers might be mounted at a different height than the others. The left walls will naturally` have to be accommodated thereto,`and their projections will therefore also come at different heights, all being o set from each other. Under these vcircumstances,each engager would coperate only with its own totalizer, and Would pass the other' totalizer Without any hindrance.

The drawings show the bars 8 8 upon which the totalizers reciprocate to be quite short, whereby the extent of rcciprocation is quite limited. But. there is nothing in this invention which thus limits the con-- struction to short bars. They may be lengthened to any extent tothe right or to the left. desired the grand totalizer might be carried by the carriage bar far enough to the lett so that its engager nose 43 will be retracted from the grand totalizer. There upon the printing carriage may proceed farther to the left to an unlimited extent for the writing ot words and figures.

Having thus described my mechanism, I claim:
